Abstract:

In this problem-based learning case, a couple who has adopted a three-year-old toddler is concerned about the child’s health, in particular the fact that the boy wheezes when he breathes. Students work in groups to analyze a variety of information and formulate a diagnosis. The case was developed for a two-semester anatomy and physiology class for undergraduates to teach them about cell physiology and tissue anatomy.

Objectives:
  • Learn that cells have an electrical potential.
  • Learn what an electrical and chemical gradient is for an ion.
  • Learn the principles behind osmosis.
  • Learn how membrane surface area and thickness influence diffusion rates.
  • Be introduced to the tissues and organs of the body and their respective functions.
  • Learn the location and function of many exocrine glands of the body.
